1. A catheter product suitable for storage until use, the catheter product comprising:
a user package sealed inside a product package;
the user package comprises a film and forms an enclosure containing a urinary catheter having a hydrophilic coating, and the enclosure contains a water-based liquid in direct contact with the hydrophilic coating on the urinary catheter; and
the product package has a first water vapour transmission rate (first WVTR) that configures the product package to be porous to water vapor, where the first WVTR is between 1 g/(m2·24 h) and 6 g/(m2·24 h) when measured at 90% relative humidity and a temperature of 38 degrees Celsius according to ASTM F1249;
wherein the first WVTR of the product package allows water vapor from the water-based liquid that exits the user package during storage to pass through the product package to adapt the user package to be dry to touch when a user opens the product package.
